I use frequently the "FileSystemObject" properties to determine the size of a file. But How determine the "Size On Dislk" value that appears on the Properties Window when we right-click a Folder/File.
That value is the related compress size value.
So All i need to know is, there's a way to determine (ex: with API, ...) the correspondent Size of a File if compressed? If "Yes", show me how to use it Please.
Please forgive me my poor english, and let me thank you in advance.
